Part 1 to the guestion you have asked, is this you tune your system to how loud you listen to it when you alone, for example you put your gain onthe amp 7o'clock or stock setting ok now you turn volume on your deck full and you turn back to 3/4 of volume, now you to amps gain and put to 9 to 930 o'clock....CLIPPING means like you hit rev limter on your car (stock that is)
